Hi! I found this Raleigh Technium Skylite Sport at a thirft store this weekend for $25. According to the serial # (R816870137) it was made in 1987. Any one seen one like it? i've searched the forum & web, but not found a match yet. I also have a couple questions; is the fork original? it doesn't to match. What size seat post did these bikes take. It Also Has a Van Schothorst stainless steel rear rim. Should I replace? Thanks for any info or suggestions!
